Abstract: A mica-filled glass fiber sheet which is smooth, of relatively low porosity, and dimensionally stable is described as is its method of manufacture. The sheet is prepared from a low-consistency aqueous slurry wherein the solids consist essentially of glass fibers, organic fibers, mica, and binder. Based on 100 parts by weight glass fibers, 3 to 15 parts by weight organic fibers, 30 to 100 parts by weight mica flakes, and 5 to 20 parts by weight organic binder are added to the water in preparing the furnish. In forming the sheet, this slurry or furnish is deposited onto a moving screen, the excess water is removed, and the wet laid sheet is dried and the binder set. In a subsequent operation, the sheet is saturated with a resin solution or latex.

Abstract: Disclosed is a self-contained evaporator type humidifier adapted to be positioned at an outlet opening of a warm air heating system and operated solely by an air stream issuing therefrom. The humidifier includes a housing provided with an air inlet opening and an exhaust air grill. A water receptacle, an adjustable water supply means, and an adjustable air-water contacting member are provided within the housing. The air-water contact member comprises a frame having a water-absorbent covering thereon and has an overall shape which is approximately that of a propeller which has been twisted at the midpoint of its longitudinal axis so that the end portions which are substantially in the shape of an elongated S, lie in planes which are generally perpendicular to each other. The air-water contact member is mounted for free rotation in journals at each end of the interior of the housing and is rotated around its longitudinal axis by the direct impingment thereon of the air stream from the heating system.

Abstract: A method of embossing wood composition board is disclosed. This method employs a water-borne base-coat composition which facilitates fine line embossing of the filled surface of wood composition board in imitation of fine grain woods, such as, for example, pecan and prima vera.

Abstract: Reticulated polyvinyl chloride plastisol foams which can be produced using mechanical frothing techniques are disclosed. These reticulated foams are sufficiently open or porous to facilitate screen printing with plastisol inks to produce thru color, decorative, cushioned floor coverings.

Abstract: Crosslinked random acrylate-ureadiacetoacetamide-diacetoacetamide copolymers are disclosed. These copolymers are prepared by the reaction of at least one polyfunctional acrylate with at least one ureadiacetoacetamide and at least one diacetoacetamide in the presence of a catalyst capable of promoting the reaction between the polyfunctional acrylate, the ureadiacetoacetamide, and the diacetoacetamide. In a preferred embodiment, the copolymers are employed to produce wear layer compositions for surface coverings.

Abstract: A process is disclosed for the making of a decorative carpet through the use of sublimable dyes. A shading effect is secured through the use of air flow control sheets that affect the flow of air through a transfer sheet and a carpet product adjacent thereto. By lessening air flow, the intensity of dye being transferred is also lessened so that shades of a certain color can be secured.

Abstract: A process of forming an embossed surface covering is disclosed. The process comprises forming a cross-linkable foam comprising at least one polymer and having a first phase region and a second phase region; heat the foam to a temperature at least equal to the flow temperature of the first phase region; compressing the heated foam and cooling the foam while compressed; cross-linking a portion of the compressed foam; and reheating the compressed foam to permit the noncross-linked portion of the foam to return or "pop back" to substantially its precompressed shape and thus form an embossed surface covering.

Abstract: A display for ceiling boards is fabricated to provide consumers with an indication of the different ceiling board designs which are available for purchase. The display is suspended at an inclined relationship for the purpose of displaying the different ceiling designs in a simulated suspended ceiling arrangement. Divider means are provided between adjacent ceiling designs to segregate the different designs and to more clearly simulate a room display for each design.

Abstract: The high gloss of vinyl composition floor coverings having a no-wax coating is maintained by using a cleaner consisting essentially of an aqueous emulsion polymerized alkali-soluble terpolymer having an average molecular weight of about 23,000, the terpolymer being an addition polymer based on about 51% by weight methyl methacrylate, 31% by weight butyl acrylate, and 18% by weight acrylic acid; a mixture of 50% by weight of the reaction product of 1 mole of coconut oil to 2 moles diethanolamine and 50% by weight of the reaction product of 1 mole dodecylbenzenesulfonic acid to 1 mole diethanolamine; an organic solvent; an aqueous ammonia solution; and water. Before being used as a cleaner the cleaner is preferably diluted to between about 0.5 to 0.10 percent solids.

Abstract: The invention is a process for forming a fiberboard structure with a rough textured surface on a conventional Oliver forming machine. The machine is operated in such a manner as to prevent the dispersion of the fibers in the slurry and to permit the fibers to build up in a lumpy and irregular manner on the rotary vacuum cylinder of the Oliver machine. Also the vacuum of the rotating clyinder is on a low vacuum level of 3-5 inches of mercury and the slurry level is maintained at point 5 inches below the center line of the rotating cylinder. There is thereby formed a fiberboard structure which has a very rough surface texture.

Abstract: A method for making a dimensionally stable decorative floor covering product. A sheet is first formed, and this is then provided with a decorative design. A clear wear layer is applied thereon, mechanically embossed-in-register, and then the sheet is cut into a plurality of individual tile units.

Abstract: Reticulated polyvinyl chloride plastisol foams which can be produced using mechanical frothing techniques are disclosed. These reticulated foams are sufficiently open or porous to facilitate screen printing with plastisol inks to produce thru color, decorative, cushioned floor coverings.

Abstract: A coloration method for textiles using chemically formed gels is disclosed. The method provides considerable freedom for making color designs and precise pattern prints, and can be used with conventional dyeing and printing equipment. In one embodiment of this invention, gelled regions are formed by separately applying a gelable composition containing alginic acid or an alginic acid derivative and a gelling agent composition to a textile material, and then over-dyeing the material, the gelled regions serving as dye resist regions.

Abstract: The invention herein is directed to a method of providing a ceiling board with a fabric facing. The fabric facing is molded to the irregular shape of the ceiling board so that there is no wrinkling or gathering of the fabric as it is shaped to the configuration of the ceiling board. The lack of wrinkling and gathering is secured without the use of a laborious hand-cutting operation.

Abstract: A window insulation system adapted for use on large metal or wood framed windows such as used in factories, schools, etc., is installed in spaced relation to a window sash on the side thereof facing the interior of a building. The system includes insulation panels which are mounted on and held in spaced relation to the window by a framework which is supported on brackets mounted on window mullions. Additional stabilization of the system may be provided by brackets which are mounted on window muntins.
